From where does the Hajj pilgrim assume Ihram on the day of At-Tarwiyyah?

Answer:

He assumes Ihram from his place just as the Companions of the Prophet Sallallahu alaihi wasallam, assumed Ihram from their places in Al-Abtah during the Farewell Hajj, according to the order of the Prophet Sallallahu alaihi wasallam. Likewise, whoever is inside of Makkah, he assumes Ihram from his place. This is due to the previous Hadith of Ibn Abbas may Allah be pleased with him, which contains the Prophet's statement: And whoever is within that- meaning within the boundaries of the Maawaqit- then his place of assuming Ihram is from his people (i.e., his home). Even the people of Makkah assume Ihram from Makkah.[1] This Hadith's authenticity is agreed upon.
